Method for Retrieving the Implemented Data Model from a Device

ABSTRACT

Presented is an apparatus and methods for collecting the implemented data model and version information from an end user device. The apparatus is communicatively connected to the end user device and uses, for example, the Broadband Forum TR-069 protocol or another protocol for communications. The method interrogates the end user device to determine all parameters and their data types by traversing the end user device&#39;s data model level by level and instantiating any objects discovered that are instantiable but not yet instantiated. The method archives the data model and end user device version information for later use with like devices.

RELATED APPLICATION

This application is related to, and claims priority from, Provisional Application No. 61/436,669, filed on Jan. 27, 2011, entitled “Method for Retrieving the Implemented Data Model from a Device” to Magnus LJUNG et al., the entire disclosure of which is incorporated here by reference.

TECHNICAL FIELD

The present invention relates generally to end user device management systems and more specifically to configuring an end user device management system for different vendor end user devices and software versions.

BACKGROUND

The number of end user devices such as set-top boxes, DSL modems, gateways, etc. has greatly increased over the last few years. In response to this growth of end user devices in the marketplace, the Broadband Forum has defined a standard for managing these types of devices. The standard is referred to as TR-069 or CWMP and is incorporated herein by reference. Included in the standard are a number of technical reports, specifying data models available for the end user devices. The data models specify objects available to the end user device, the parameters associated with the objects and other information such as an indication whether the parameters are available for change through a communication link.

The Broadband forum provides schema and definition files for each data model allowing an end user device management system to import the data model files and manage the device. As the market for end user devices has evolved, most vendors have extended the data models provided by the Broadband Forum to include vendor specific objects and parameters to provide distinctive features for the vendor's products. The extension of the standard data models with vendor specific objects and parameters has proven problematic to end user device management systems. In one example of the associated problems, many vendors do not provide a data model definition in a standard format that an end user device management system can import or if a data model is provided, it typically is out of date with the objects and/or parameters implemented in the end user device. In another example, although a particular vendor may provide up-to-date data model files for the current version of their software, they do not provide data model files for previous versions of their software.

The result of this evolution is that users of an end user device management system must manually define the vendor extensions in the end user device management system or encourage each vendor to release data model files, including the vendor's extensions, for each version of the vendor's software released to the market. Consequently, market pressure is building for a mechanism allowing reliable and version complete support of end user device data models in an end user device management system without any error prone manual data entry.

SUMMARY

Apparatus and methods address the market needs described above by providing an automatic generation of the data model, including the vendor extensions, for end user devices. The end user device management system communicates with an end user device currently configured with the software version and data model of interest. As a part of this communication, the end user device management system extracts the implemented data model, including the vendor extensions, from the end user device. The end user device management system stores the data model and information describing the end user device and the software version as metadata for use with future end user devices executing this version of the vendor's software.

In one exemplary method embodiment, the end user device management system establishes a communication link to an end user device of interest. In another aspect of the exemplary method embodiment, the end user device management system downloads the end user device information from the end user device. In the exemplary method embodiment, the end user device information comprises parameter names, parameter data types, multi-instance objects, and information associated with each parameter indicating whether each parameter is writeable. Continuing with the exemplary method embodiment, the end user device management system processes the end user device information to determine if there are any objects that require instantiation and requests the end user device to instantiate those objects. The exemplary method embodiment, after completing the interrogation and processing, archives the data model and version information to a data storage device.

It should also be noted in the exemplary embodiment that the information remote storage 502 can be shared by a plurality of end user device management systems 102.

Turning now to FIG. 6, illustrated is an exemplary embodiment 600. The exemplary embodiment 500 depicts the signaling flow for an end user device management system 102 initiating a connection to an end user device 104 using the TR-069 protocol. First, at exemplary embodiment step 601, the end user device management system 102 sends a connection request to the end user device 104 asking the end user device 104 to contact the end user device management system 102. Next in the exemplary embodiment, at step 602 the end user device 104 contacts the end user device management system 102 by sending an Inform request towards the end user device management system 102. Continuing at step 603 with the exemplary embodiment, the end user device management system 102 sends an inform response toward the end user device 104. Continuing with the exemplary embodiment, at step 604, the end user device 104 indicates it has nothing more to do by sending an empty HTTP Post.

Further in the exemplary embodiment, at step 605, the end user device management system 102 send a GetRPCMethods request command toward the end user device 104 to determine the capabilities of the end user device 104. Continuing with the exemplary embodiment at step 606, the end user device 104 responds with a GetRPCMethods response and a list of all remote procedure call (RPC) methods supported by the end user device 104.

Next in the exemplary embodiment, at step 607 the end user device management system 102 sends a GetParameterNames request command toward the end user device 104. It should be noted that the argument to this RPC is an empty string to indicate that the end user device 104 should return all object and parameter names supported by the end user device 104. It should also be noted that the end user device 104 will also provide information indicating if the objects are instantiable and parameters are writeable. Continuing with the exemplary embodiment, at step 608 the end user device 104 will answer with a GetParameterNames response including all parameter and object names and whether each parameter is writeable and each object is instantiable. Further in the exemplary embodiment, the GetParameterNames response also includes an indication for each object name whether or not the object is instantiated.

Continuing at step 609 of the exemplary environment, for each object that is not instantiated and is instantiable, the end user device management system 102 sends an AddObject request command to the end user device 104. It should be noted in the exemplary embodiment that this allows the method to discover parameters and sub-objects associated with the data model implemented on the end user device 104. Next in the exemplary embodiment, the end user device 104 instantiates an instance of the requested object including all parameters contained in the object. Further in the exemplary embodiment at step 610, the end user device 104 answers with an AddObject response and an instance ID of the instantiated object sent toward the end user device management system 102 which then saves the instance ID of the object for further access. It should be noted in the exemplary embodiment that this sequence of steps, 609-610, is repeated for each object requiring instantiation, including the objects appearing as sub-objects to the instantiated object.

Continuing with the exemplary embodiment, at step 611 the end user device management system 102 sends a GetParameterNames request command using the instance ID returned for the instantiated object toward the end user device 104. Further in the exemplary embodiment, at step 612 the end user device 104 answers with a GetParameterNames response including all the parameters associated with the instantiated object and an indication for each parameter as to whether the parameter is writeable. It should be noted that steps 609-612 are repeated for all instantiable objects, including instantiable objects appearing as sub-objects under an instantiated object. It should also be noted in the exemplary embodiment that as an alternative to steps 609-612, the end user device management system 102 can instantiate all objects on one level and then send a GetParameterNames command on the root level and search for instantiable objects on the next lower level, send an AddObject command for each discovered instantiable object and send another GetParameterNames command on the root level to discover the next lower level instantiable objects. In the exemplary embodiment, this process is repeated until all instantiable objects and writeable parameter names have been discovered.

Continuing with the exemplary embodiment, at step 613 the end user device management system 102 sends a GetParameterValues request for each parameter name to discover the data type of each of the parameters. Further in the exemplary embodiment, the end user device answers at step 614 with a GetParameterValues response that comprises the parameter name, parameter value and the parameter value data type. It should be noted in the exemplary embodiment that the end user device management system 102 stores at least the parameter name and the parameter value data type as a part of the data model. Continuing with the exemplary embodiment, the end user device management system 102 at step 615 sends a DeleteObject request command, including at least the instance ID, for each object instantiated at the request of the end user device management system 102 and at step 616 the end user device answers with a corresponding DeleteObject response. Next, at step 617, the end user device management system 102 sends an empty HTTP response toward the end user device 104 and the end user device 104, at step 618, closes the connection. It should be noted in the exemplary embodiment, that once the steps are completed the end user device management system 102 has collected all parameter names, all multi-instance objects, information associated with each parameter name identifying whether the parameter is writeable and information associated with each parameter identifying the parameters data type.

Continuing at FIG. 7, an exemplary method embodiment 700 for collecting and archiving, by an end user device management system 102, the implemented data model and version information from an end user device 104 is depicted. Starting at step 702, the exemplary method embodiment 700, using the communication component 106, establishes a connection with a selected end user device 104. In the exemplary embodiment method 700, the connection is established using the TR-069 protocol component. Continuing with the exemplary embodiment at step 704, the end user device management system 102 downloads the data model and version information from the end user device 104. In the exemplary embodiment, data model information comprises all parameter names, all multi-instance objects, data associated with each parameter name indicating whether the parameter is writeable and data associated with each parameter indicating the data type of the parameter. It should be noted that the data model information is downloaded by a series of requests and responses as described above for FIG. 6.

Next, at step 706, the end user device management system 102 processes the information collected from the end user device 104. In the exemplary embodiment method, the end user device management system 102 interrogates the end user device 104 for all objects that are instantiable but not yet instantiated and instantiates these objects to determine if there are any sub-objects that are instantiable and require further processing. The exemplary embodiment method continues with this method of processing objects and parameters until the complete data model implemented in the end user device 104 has been determined. The exemplary embodiment then combines this information with the version information associated with the end user device and presents this combined information for archiving. At step 708 of the exemplary embodiment, the end user device management system 102 archives the data model and version information to storage device. In the exemplary embodiment, the archived information can be used at a later time to manage a device that is compatible with the version information associated with the data model. In one aspect of the exemplary embodiment, the storage device can be a local storage device associated with the end user device management system 102. In another aspect of the exemplary embodiment, the storage device can be a remote storage device operating independently but communicatively connected to the end user device management system 102 or it can be part of another device including but not limited to a server, providing storage services, on a network accessible by the end user device management system 102.

Other input devices can include a microphone, joystick, game pad, satellite dish, scanner, or similar devices. These and/or other input devices can be connected to the processing unit 820 through user input 840 and associated interface(s) that are coupled to the system bus 890, but can be connected by other interface and bus structures, such as a parallel port, game port or a universal serial bus (USB).

A graphics subsystem can also be connected to the system bus 890. In addition, a monitor or other type of display device can be connected to the system bus 890 through an interface, such as output interface 850, which can in turn communicate with video memory. In addition to a monitor, computers can also include other peripheral output devices, such as speakers and/or printing devices, which can also be connected through output interface 850.

The computer 810 can operate in a networked or distributed environment using logical connections to one or more other remote computers, such as remote server 870, which can in turn have media capabilities different from device 810. The remote server 870 can be a personal computer, a server, a router, a network PC, a peer device or other common network node, and/or any other remote media consumption or transmission device, and can include any or all of the elements described above relative to the computer 810.

In a networked environment, program modules depicted relative to the computer 810, or portions thereof, can be stored in a remote memory storage device. It should be noted that the network connections shown and described are exemplary and other means of establishing a communications link between the computers can be used.

Additionally, it should be noted that as used in this application, terms such as “component,” “display,” “interface,” and other similar terms are intended to refer to a computing device, either hardware, a combination of hardware and software, software, or software in execution as applied to a computing device implementing a virtual keyboard. For example, a component may be, but is not limited to being, a process running on a processor, a processor, an object, an executable, a thread of execution, a program and a computing device. As an example, both an application running on a computing device and the computing device can be components. One or more components can reside within a process and/or thread of execution and a component can be localized on one computing device and/or distributed between two or more computing devices, and/or communicatively connected modules. Further, it should be noted that as used in this application, terms such as “system user,” “user,” and similar terms are intended to refer to the person operating the computing device referenced above.

Further, the term to “infer” or “inference” refer generally to the process of reasoning about or inferring states of the system, environment, user, and/or intent from a set of observations captured from events and/or data. Captured events and data can include user data, device data, environment data, behavior data, application data, implicit and explicit data, etc. Inference can be employed to identify a specific context or action, or can generate a probability distribution over states, for example. The inference can be probabilistic in that the computation of a probability distribution over states of interest based on a consideration of data and events. Inference can also refer to techniques employed for composing higher-level events from a set of events and/or data. Such inference results in the construction of new events or actions from a set of observed events and/or stored event data, whether or not the events are correlated in close temporal proximity, and whether the events and data come from one or several event and data sources.

The above-described exemplary embodiments are intended to be illustrative in all respects, rather than restrictive, of the present innovation.
